Cokin P056 P-Series Star 8 Effect Filter

The Cokin P056 Star 8 is a creative effect filter from Cokin's P-series (M-size) line, designed to transform any point light source in your frame into an eye-catching eight-pointed star pattern. The effect is produced by a finely etched cross-hatch grid on the filter surface, which diffracts light rays outward from highlights such as streetlamps, candle flames, sun reflections on water, or specular highlights on metallic surfaces. The result is a glittering, glamorous quality that can elevate night cityscapes, holiday lighting scenes, and backlit portraits without any post-processing work.

As a P-series filter, the P056 slots into Cokin's modular rectangular holder system, which mounts to your lens via screw-in adapter rings available in a wide range of thread sizes. This means a single filter can be shared across all your lenses. The rectangular design also allows you to rotate the filter within the holder to orient the star points at your preferred angle. Because the filter is essentially clear apart from its etched pattern, it introduces negligible color shift and minimal light loss, so exposure compensation is generally not required. The filter measures approximately 84mm wide, consistent with the P-series standard, and is constructed from Cokin's optical resin, which keeps the weight and cost low while still delivering a clean, well-defined star effect.
